' WOODWORKlNG MACHINE.

- Patented Nov. 6, 1908.

To all whom it may concern:

Be it knowmthat I, ELWIN S. Bnnrng'a citizen of the United States, and a resident of Putnamville, in the county of Washington and State of Vermont, have invented a new and Improved Woodworking-Machine, of which the following is a full, clear, and exact I description.

My invention relates to a machine forceperatmg upon wood and similar materials, and while capable of general use is especiallv ada ted to making blanks from which clot 18S-PlI1S are to be manufactured. It will therefore be described with ence to this manufacture.

The principal objects of the invention are particular referto provide means for feeding and holding the blanks for grooving op osite surfaces thereof and for beveling the e ges.

Further objects of the invention are to provide :fOI' certain adjustments and variations in the shape of the blank.

Reference is to'be had to the accompanying drawings, forming a part of this specification. in which similar characters ofreference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a machine, showing the principle of my invention, partly in section, on the line 1 1 of Fig. 2. Fig. 2 1s a plan of the same. on an enlargedscale, on the line 3 3 of Fig. 1. Fig. 4 is an end view of a cutter-head. Fig. 5' is an end elevation of an adjustable sawframe constituting part of the invention. Fig. 6 is a side elevation of the same. Fig. 7 is a pers ective view of the blank formed by the mac inc when set up in the manner illustrated, and Fig. 8 is a perspective view of the clothes-pin which can be made from the.

blank.

Referring first to Fig. 8, it will be seen that the clothes-pin is composed of two halves a a, connected together by a spring I), which passes across the top of one of.the halves. These halves of the pin are formed from the blank 0 (shown in Fig. 7) by s litting it transversely. In order to'provi e' for the configuration of the clothes-pin, this blank is in the present instance formed with two grooves c on its upper surface and with a groove c on its lower surface, this latter groove being designed to rovide for the reception of the w1re b. he blank is also beveled upon inclines c? and-con its opposite Fig. 3 is a sectional view,-

edges, one to form the line end of the clothes-pin and the other the tail end.- In manufacturing this blank a block is first cut of-the width, thickness, and'is then put ii to the machine.

Referring to ig. 3, the operation of the machine for producing the blank 0 will be described. The blank is fed longitudinall in the machine-by means of a traveling be 10., In the course of its passage through the machine it is operated upon by cutters 11 on a cutter-head 12, which in turn is mounted on a shaft 13. These cutters are provided with and length required the necessary configuration at their edges to form the grooves 50. On the under side of the blank is located a saw 14 for cutting the groove 0 This saw is mounted on a shaft 15. Upon the .0 posite sides of the path through which the blank passes are two saws 16 and 17, mounted on an inclinefoi the purpose of cutting the inclined faces 0 on a frame 18, under which. is a shaft (not shown) from which a belt 19 is operated. This belt passes over an idler-pulley 20, mounted on a sliding block 21. This block is connected by a link 22 with a lever 23, pivoted to the lower part of the frame or floor. The manipulation of this lever is intended to slide the .block' 21 back and forth and increase or"decrease the ressure 0f the idler upon the belt/'19, ,and thus effect the opera-. tion of the belt u on a pulley 24, which it operates. This puiley is mounted upon a shaft 25, which carries a pinion 26, meshing with a gear 27. This gear is mounted on a shaft 28,- which is provided with s rocket-wheels 23 for carrying an endless c ain 38, which is composed of a series of plates 31, having pro jections' 32 for engaging the sockets of the sprocket-wheels, and which constitutes a movable bed for supporting the work of the machine. This movable bed passes over a s rocket-wheel33, similar in all respects to t e sprocket-wheels 29, and mounted on a I1aft'34. 1

The shafts 28 and 34 are mounted in bearingsvupon the frame, and the latter shaft is illustrated for accom belt 49, a pulley 50 on the shaft 15.

provided with a hand-wheel 35, by means of which the movable bed can .be operated when the power is not applied. For exam- 1 pie, if the work in passing through the maa press-plate 36. This press-plate extends thrmighout the length of the main portion of the machine and" is composed of two alined sections spaced apart from each other for a purpose to be hereinafter described and is provided with one or more latens 37 for holding it against the work and holding the work in proper position for receiving the desired operations. Each platen is provided with a plunger 38, a spring 39, and an adjustable collar 40. The plunger is mounted to reciprdcate in a frame 41', secured to the frame 18.

The parts of the machine so far described provide for feeding the work along in the ma chine and holding itin the proper position, also for feeding the work by hand to remove it l'rom the machine when desired. The sectimes of the press-plate are spaced apart, as at 42, to provide a space for the cutterhead 1.2, which has been described above. "l3, upon which. this cutter-head is mounted, is provided with a pulley 43, driven by a belt 44 from a pulley 45, which receives power through a belt 46 from the shaft above mentioned as being below the floor. The pulley is mounted. on a shaft 47, which is also provided with a pulley 48, that drives, through a The shaft 47 therefore operates the cutter-head and the saw 14.

In order to provide for opeiating the saws 16 and 17, two pairs of 1nulepulleys 51 are operated from a coul'iter-shaft located under the center of the machine and in alinement with the saws. '.l.hese ulleys are niounted on brackets 52, which 5 ide up and down onv standards 51-1 and are secured in adjusted poon thereonby means of screws 54. These d -re provided with bolts 55 and 56, recely, designed to operate the saws The shaft through the instrumentality of pulleys 5'4 and 58, which are mounted on the shafts 59 and 60, on which the saws are mounted. The object in making the mule-pulleys adj ustable is to provide for adjusting the angle at which the saws cut the blank. In order to do this, the shafts upon which the saws are mounted are canted, and it will be readily seen that the mule-pulleys must he raised and lowered, so as to properly drive the; belts passing to the pulleys 57 and 58.

The way in which the canting is provided for is shown in Figs. 5 and 6.. In these figures one of the saws-as, for example, the saw 16,-

.which is mounted on the shaft 59-is located 6;;

on a bracket 61. This bracket has bearings 62 for the shaft, and the shaft is adapted to slide longitudinally to a slight extent in said bearings. A screw 63 is provided for making a longitudinal adj ustmcnt. The bracket 61 is provided with a face-plate 6 having longi tudinal slots 65. T hrough these, slots pass bolts 66 into a stationary brack t 67 on the frame 18 of the machine. By loosening the bolts 66 the bracket 6] can be tilted in either 7 direction or raised or lowered so as to pro vide for changing the thickness of the blank and the angle of the cut. The other saw is mounted in the same way and is provided with the same kind of adjustments. 8t

Having thus described my invention, '1 claim as new and desire to secure by Letters Patent- A woodworking machine comprising a traveling bed for carrying, the work, a prcssure-plate comprising alined sections spaced apart to orm an opening, a cutter-head projecting through said opening, inclined saws upon each side of the traveling bed and in ac.-

vance of the cutter for acting upon the sides 9 ol the work, a vertical saw arranged beneath the bed and in advance of the inclined saws, and means for operatil'igr said parts in unison. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
